What makes Intuniv different?
The time-release kinetics of Intuniv make the difference. The quick absorption of immediate-release guanfacine causes the nervous system to fight the effects of the medication -- or immediate-release stimulants, for that matter -- when it is released, in a rush, into the bloodstream. You experience that “fight” as side effects. The extended, gradual release of Intuniv doesn’t seem to elicit this reaction in the nervous system.
